If you're greatly concerned then wait for the official new release. But I personally would have confidence in it. Depends whether it's the mac or windows version though.

BTW reading the beta reports by others will give you an idea if there are serious problems or not. Or simply just the odd simple bug. It will also help you to see the advantage of the new improvements. But only use it if you feel confident. Beta testing is mostly for finding out if there's problems with new developments & additions. But sometimes the beta is so good it becomes the official version. Some people like to use the new improvements immediately.
